How to re-install adobe creative suite 6 after my computer was re-booted

I purchased a copy of Adobe Creative Suite 6 (for a Mac) from George Brown College in Toronto Ontario, in 2014.

Recently, my computer had to be re-booted, and now I have to re-install this program. I have a serial number and an ID, but when I insert the disc, nothing happens, and I am not able to enter this information.

Can someone please assist me with respect to reactivating this software?

Thanks very much.
